The Laptop Thin (7mm) SSHD from Seagate has a 64MB Cache and comes equipped with 8GB of MLC NAND Flash. At less than a year old the Laptop Thin is relatively new, but its performance is unbalanced and favours small file IO. With average sequential speeds of 85 MB/s the Laptop Thin lags the group leaders by over 50% in this area. As a result regular tasks such as copying multimedia files will be relatively slow on this drive. On the other hand, thanks to its 8GB of NAND flash, small file performance is far better and average and lies in the region of 3 MB/s which is a very respectable result. Overall the Laptop Thin's performance profile is skewed heavily towards small file IO. The Thins larger capacity 1TB sibling offers considerably better value for money. [Jan '14HDrivePro]

The 1TB Barracuda 7200.14 boasts impressive peak sequential read/write Lab speeds of 195/193 MB/s. These best case burst speeds indicate what the Barracuda is capable of under Lab perfect test conditions. Our real world benchmarks have been sourced from hundreds of users and give a better sense of how well this drive actually performs on a day to day basis. The 1TB 7200.14 has an average UBM sequential read/write speed of 147 MB/s, which is a superb result, especially for a budget drive. With 4K random read/write speeds of 0.77/1.53 MB/s small file performance is also respectable making the 1TB Barracuda a very good all round performer. In terms of value for money the relatively small 1TB drive is not as good value as its larger 3TB sibling but in the 1 TB category this is one of the best value for money drives available.
